World War I in Photos: Animals at War

Animals were used in World War I on a scale never before seen -- and never again repeated. Horses by the millions were put in service as cavalry mounts and beasts of burden, but they were not the only animals active in the war. Mules, dogs, camels, and pigeons all played vital roles, as well as many others -- all at great risk, and with heavy cost.

When the war began, Europe's armies had an understanding of warfare that put the use of cavalry in high regard. Soon, however, the deadly terrain that evolved around trench warfare rendered cavalry attacks nearly useless on the Western Front. But the need for constant resupply, movement of new heavy weaponry, and the transport of troops demanded horse power on a massive scale -- automobiles, tractors, and trucks were relatively new inventions and somewhat rare. British and French forces imported horses from colonies and allies around the world, a near-constant flow of hundreds of thousands of animals across the oceans, headed for war. One estimate places the number of horses killed during the four years of warfare at nearly 8 million. Other animals proved their usefulness as well: Dogs became messengers, sentries, rescuers, and small beasts of burden. Pigeons acted as messenger carriers, and even (experimentally) as aerial reconnaissance platforms. Mules and camels were drafted into use in various war theatres, and many soldiers brought along mascots to help boost morale. Only a couple of decades later, at the onset of World War II, most military tasks assigned to animals were done by machines, and warfare would never again rely so heavily on animal power. On this 100-year anniversary, I've gathered photographs of the Great War from dozens of collections, some digitized for the first time, to try to tell the story of the conflict, those caught up in it, and how much it affected the world. Today's entry is part 4 of a 10-part series on World War I, which will be posted every Sunday until June 29. Come back next week for Part 5.

A single soldier on his horse, during a cavalry patrol in World War I. At the start of the war every major army had a substantial cavalry, and they performed well at first. However, the development of barbed wire, machine guns and trench warfare soon made attacks from horseback far more costly and ineffective on the Western Front. Cavalry units did prove useful throughout the war in other theatres though, including the Eastern Front, and the Middle East. (National Library of Scotland)

Unloading a mule in Alexandria, Egypt, in 1915. The escalating warfare drove Britain and France to import horses and mules from overseas by the hundreds of thousands. Vulnerable transport ships were frequent targets of the German Navy, sending thousands of animals to the bottom of the sea. (Bibliotheque nationale de France) #

Sergeant Stubby was the most decorated war dog of World War I and the only dog to be promoted to sergeant through combat. The Boston Bull Terrier started out as the mascot of the 102nd Infantry, 26th Yankee Division, and ended up becoming a full-fledged combat dog. Brought up to the front lines, he was injured in a gas attack early on, which gave him a sensitivity to gas that later allowed him to warn his soldiers of incoming gas attacks by running and barking. He helped find wounded soldiers, even captured a German spy who was trying to map allied trenches. Stubby was the first dog ever given rank in the United States Armed Forces, and was highly decorated for his participation in seventeen engagements, and being wounded twice. (Wikimedia Commons) #

"These homing pigeons are doing much to save the lives of our boys in France. They act as efficient messengers and dispatch bearers not only from division to division and from the trenches to the rear but also are used by our aviators to report back the results of their observation." (WWI Signal Corps Photograph Collection) #

In the background there are two mobile pigeon lofts and a number of tents. The soldier in the middle has the grenade badge of the Royal Engineers over the chevrons which show he is a sergeant.

A message is attached to a carrier pigeon by British troops on the Western Front, 1917. One of France's homing pigeons, named Cher Ami, was awarded the French "Croix de Guerre with Palm" for heroic service delivering 12 important messages during the Battle of Verdun.

Horses requisitioned for the war effort in Paris, France, ca. 1915. Farmers and families on the home front endured great hardship when their best horses were taken for use in the war. (Library of Congress) #

Dead horses and a broken cart on Menin Road, troops in the distance, Ypres sector, Belgium, in 1917. Horses meant power and agility, hauling weaponry, equipment, and personnel, and were targeted by enemy troops to weaken the other side -- or were captured to be put in use by a different army.
